Abstract

In this study the amount of neutral and acidic glycosaminoglycans in the zona pellucida and antrum of primary, preovulatory, and atretic follicles was analyzed. Serial sections of preovulatory hamster follicles were stained with PAS or alcian blue to estimate the content of neutral and acidic glycosaminoglycans, respectively. The amount of hyaluronic acid, chondroitin sulfate and sialic acid was determined using enzyme digestion procedures followed by alcian blue staining. Microdensitometric analyses showed that the strongest PAS staining was in the zona pellucida of atretic follicles, less staining in preovulatory follicles but more than in the antrum of preovulatory follicles. No hyaluronic acid was found in the zona pellucida of any follicular type, but there was a measurable amount in the antrum of preovulatory follicles. Chondroitin sulfate was present in the zona pellucida of primary and atretic follicles, as well as in the antrum of preovulatory follicles. Sialic acid was present in the antrum and zona pellucida of all follicular types. Sialic acid plays a role in receptor recognition and its presence may reflect the role of the zona pellucida in sperm recognition and fertilization.
